What I did was separate the data into three separate CADD files. Cleaned up the survey points and linear features as if each CADD file represented a single isolated survey. Then created terrain Models. Then cleaned up crossing break lines and so on and so on...</p> <p>Actually, I made this more complex than it was. I was looking for some &quot;magic&quot; boundary tool... then create three terrain models within the same file.</p> <p>Thanks again.</p><div style="clear:both;"></div>RE: Create Three Terrain Models Three Sites which are Geographically Separatedhttps://communities.bentley.com/thread/481950?ContentTypeID=1Tue, 18 Sep 2018 07:39:41 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:92da0d9f-22bf-451b-a7e1-2fdab73fdc0fMark Marnell<p>Could you not just reference the relevant data into separate files i.e. one of CADD data, one for field book, one for data files, and then create a terrain in each file using a terrain filter? Or just manually select the data for each terrain (if it is all in one file) - slower method as you would have to select break lines, then spots etc?&nbsp;</p><div style="clear:both;"></div>
